Abstract (en)

A conversion device (50), particularly for a split tool tamper (10), serves to translate a rotational motion, e.g. from a motor shaft, to a reciprocal motion about an output or tool shaft (90). It is structured to be coupled to a rotating shaft (40) of a motor (11) and to an assembly comprising a tool shaft (90). The axis of the tool shaft (90) extends generally perpendicular to the axis of said motor shaft (40). The conversion has an eccentric hub (52) having a disk (56) with a perimeter, and a sidewall (57) extending from said perimeter and forming a recess (60). The disk (56) is structured to be coupled to said motor shaft (40). A yoke (80) having a shaft (81) with an axis and a pivot pin (84) is pivotally coupled to the assembly. The conversion device (50) including the eccentric hub (52) and the disk (56) causes in a simple manner the tool shaft (90) to move in reciprocal motion.
